This work is part of a larger project to look at the total design and testing of a new design of helmet for improved peripheral vision and comfort for use when driving a racing car. A key point in the project is the bespoke nature of the helmets. A digitalized image of the head is made that is then used to customize the helmet. Specialized computational packages are then used to design the helmet, translate that image into geometry or a surface mesh to be used within CFD and other analysis packages such as finite element analysis. Computational techniques can then be used to assess the improvement in terms of peripheral vision, safety and comfort in comparison with a standard helmet. The use of computational techniques allows the helmet to be truly bespoke; allowing for different head shapes and sizes and unique features such as ribs for increased aerodynamic stability, or the shaphe, position and size of ventilation inlets and outlets. This part of the project looks at the use of Computational Fluid Dynamics (CFD) to test designs for improved ventilation, aerodynamic capabilities and comfort factors such as solar heating and aerodynamic forces on the helmet.
